JAMES L YONS, OF DUBUQUE, IOWA.

STOVE ORFURNACE.

SPECIFICATION forming part of Letters Patent No. 537,054, dated April 9,1 895.

T0 at whom it may'concern:

Be it known that I, JAMES LYONS, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in .the art to which it appertains to make and use the same. I

My invention has relation-to heating stoves, the primary object in view being to provide a stove whereby a more perfect combustion of the fuel is obtained and the gases, soot and smoke usually produced in stoves, entirely or substantially consumed, whereby I effect a great savingof fuel.

A further object of my invention is to provide a stove whereby a thorough and perfect ventilation of the room may be obtained.

Other objects and advantages of my invention will appear hereinafter, and with the various objects in view the invention consists in the novel construction, arrangement and combination of parts as hereinafter fully described, illustrated in the drawings and pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a stove embodying my invention. Fig. 2 is a vertical section thereof. Fig. 3 is a horizontal section on' line m-w; Fig. 4, a similar View of a slightly modified construction of stove.

My invention is adapted to be utilized in the construction of heating stoves using either soft or hard coal for fuel and in the drawings I have'illustrated a construction of heating stove whereby perfect combustion of all gases, soot and smoke is obtained and in order that my invention may be clearly understood I will proceed to describe the same in detail reference being had more particularly to Figs. 1, 2, 3 and 4.

A indicates a stove embodyingmy invention, said stove having the exterior shell or casing B, which'is supported upon a base 0, mounted on suitable legs. Within the base is a suitable ash pan D.

Centrally arranged within the stove is a perforated open ended cylinder E which extends from the apex or upper end of the stove to a Application filed April 13, 1894. 'san1n0.6o7,402. (No model.)

point adjacent to the lower end of the casing and grate F.

Within the cylinder E is arranged a cone G, the lower or small end of which terminates within the cylinder E and adjacent to the lower end of the latter.

H indicates a dome or cover which is adapted to close the upper ends of the cylinder and cone and is provided with a number of perforations J to permit air from the room entering the stove to promote the combustion as pres ently described.

Within the lower portion of the stove, are arranged several perforated cones K which set immediately over openings K of the grate and are open at both ends. The cones K are arranged with their small ends uppermost and terminate somewhat above the lower end of the cylinder E.

Within the upper portion of the stove I arrange a horizontal partition L which thus forms an upper chamber M and thelower or combustion chamber N. The partition L is provided with an opening 0, and also with a similar opening P adjacent to opening 0, said openings being separated by means of a partition Q arranged vertically within the upper chamber M. a suitable damper R and a smoke pipe S com municates with the chamber M, at a point adjacent to the opening P. a

T indicates a flue or passage provided in e the stove and having its discharge end immediately beneath the grate, said flue T serving to conduct air from the room to the fire on the grate, which air becomes heated in traversing the fiue. Thus additional ventilation is afforded for the room.

A pipe U may be provided as seen in dotted lines Fig. l which may lead from an upper room to the inlet end of line T and thus ventilate said upper room.

Instead of introducing the air from within the room through a perforated cover H, I may employ a closed cover and provide a number of horizontally arranged pipesV leading from the outside of the stove to the interior of the cylinder and cone as seen in Fig. 4. I however prefer the first described construction.

When the stove is in use the vitiated air within the room will enter the openings of The opening P is provided with gases, soot and smoke, and the damper to opening P having previously been closed any unconsumed particles of soot or gases and smoke will pass through the opening, O, and owing to the arrangement of-partition' Q are caused to travel around the cylinder and in their passage they become highly heated and are practically consumed.

If desired the damper R may be opened-to thus provide a direct draft for the products of combustion to the pipe S. It will also be seen that the heated air entering below the grate from flue '1 passesupthrough the grate and through the cones thereonand the fuel surrounding them and causes the gases, soot and smoke to be consumed.

lVhat'I claim, and desire to ters Patent, is

1. In a stove, the combination withthe shell or casing thereof, and the grate, of a perforated cylinder arranged verticallywi thin the secure by, Letcasing and extending from thetop thereof to a point somewhat above the grate, a cone arranged within said cylinder, and having its lower end adjacent to. the lower end oli the latter, air ducts or openings leading into theupper end of the cone, a horizontal partition dividing the interior of the casinginto two chambers, a vertically arranged partition in" the upper chamber, an opening in said horizontal partition on one side of the vertical partition and a smoke pipe comingwithin the said upper chamber, for the purpose specified.

2. In a stove, the combination with the shell or casing thereof, and the grate, of a perforated cylinder arranged vertically within the casing and extending from the top to a point somewhat above the grate, a cone arranged within said cylinder and having its lower end adjacent to the lower end of the latter, air ducts or openings leading into the upper end of the cone, a horizontal partition dividing the interior of the casing into two chambers, a vertically arranged partition in the upper chamber, openingsin the said horizontal partition on opposite sides of the vertical partition, a damper for one of said openings and asmoke pipe communicating with the said upper chamber, for the purpose specified.

3. In a stove, the combination with the shell or casing thereof andthe grate, ot a perforated cylinder arranged vertically within the casing and extending from the top to a point somewhat above the grate, a cone arranged within the said cylinder and having its lower end adjacent to the lower end of the cylinder, air duct'sor openings leading into the upper end of the I cone, and horizontal partitions within the casing and dividing the latter into two chambers a vertical partition arranged within the up-perchamloer, openings in said horizontai partition on opposite sides of the vertical partition, one ot' said openings being provided with a damper,- a smoke pipe conmeeting with said upper chamber an air duct or passage arranged alongoue side of the casing and leading from the outside of the stove and discharging beneath the grate, and perforated cones arrangedabove thegrate and extending somewhat above the latter.

In testimony whereof I affix my signature in presence of two witnesses.
